Is it possible and if it is would it be too much to ask...
You mention the ability where the game isn't over unless all 4 die. Is it possible to do this with just the regular setup without the 4 Player part? And if so, is it possible to just get a mod that have just that feature? Thanks.
It is tied in with the player script, which is why it doesn't affect the 4 players. But I guess if all 4 died with a companion left, it would get the same result.
It might be a good idea to add 5, 6 or 8 (August) for new companions, maybe you can mod it to make it as a SUMMON UI (Next to player profile UI)?
Once we (the community) gets some successful flash creation going, we should be able to start employing all sorts of features. An idea might be to have a better 'respec' option so you can still keep learnt spells, rather like a merger of the mirror and initial set-up.
First goal of this mod is to get a four-player vanilla experience. After that, I may experiment with a lot of smaller features and perhaps a few 'mod resources' where other people can implement things in their own mod.
